Answer» Answer: Let RATIO between shirt MATERIAL and trouser material be 3x:2x3x:2x. The cost of shirt material = 50\times3x=150x50×3x=150x The selling price at 12% gain = \frac{100+P\%}{100}\times CP 100 100+P% ×CP = \frac{100+12}{100}\times150x 100 100+12 ×150x = \frac{112}{100}\times150x=168x 100 112 ×150x=168x The cost of trouser material = 90\times2x=180x90×2x=180x The selling price at 12% gain = \frac{100+P\%}{100}\times CP 100 100+P% ×CP = \frac{100+10}{100}\times180x 100 100+10 ×180x = \frac{110}{100}\times180x=198x 100 110 ×180x=198x According to the question, 168x+198x=36,600168x+198x=36,600 \Rightarrow366x=36600⇒366x=36600 \Rightarrow x=\frac{36600}{366}=100⇒x= 366 36600 =100 METERS.

Answer»

Answer:

Let RATIO between shirt MATERIAL and trouser material be 3x:2x3x:2x.

The cost of shirt material = 50\times3x=150x50×3x=150x

The selling price at 12% gain = \frac{100+P\%}{100}\times CP

100

100+P%

×CP

= \frac{100+12}{100}\times150x

100

100+12

×150x

= \frac{112}{100}\times150x=168x

100

112

×150x=168x

The cost of trouser material =

90\times2x=180x90×2x=180x

The selling price at 12% gain = \frac{100+P\%}{100}\times CP

100

100+P%

×CP

= \frac{100+10}{100}\times180x

100

100+10

×180x

= \frac{110}{100}\times180x=198x

100

110

×180x=198x

According to the question,

168x+198x=36,600168x+198x=36,600

\Rightarrow366x=36600⇒366x=36600

\Rightarrow x=\frac{36600}{366}=100⇒x=

366

36600

=100 METERS.

Now, trouser material = 2x=2\times1002x=2×100

= 200 meters

Hence, Hasan bought 200 meters of the trouser material.

Answer» Answer: Radius of the cylinder = 7 cm Step-by-step explanation: GIVEN Curved surface area of a cylinder = 220 cm HEIGHT of cylinder = 5 cm TO FIND Radius of the cylinder. FORMULA USED Curved surface area of cylinder = 2πrh sq. unit Where, Radius is denoted as r. Height is denoted as h. USING FORMULA TO FIND RADIUS Curved surface area of cylinder = 2πrh sq. unit → 220 = (2 × 22 × r × 5)/7 → 220 × 7 = 220r → r = (220 × 7)/220 → r = 7 ∴ Radius of the cylinder = 7 cm

27.

if the curved surface area and the height of the cylinder are 220cm square and 5 cm then its radius will be

Answer»

Answer:

Radius of the cylinder = 7 cm

Step-by-step explanation:

GIVEN

Curved surface area of a cylinder = 220 cm
HEIGHT of cylinder = 5 cm

TO FIND

Radius of the cylinder.

FORMULA USED

Curved surface area of cylinder = 2πrh sq. unit

Where,

Radius is denoted as r.
Height is denoted as h.

USING FORMULA TO FIND RADIUS

Curved surface area of cylinder = 2πrh sq. unit

→ 220 = (2 × 22 × r × 5)/7

→ 220 × 7 = 220r

→ r = (220 × 7)/220

→ r = 7

∴ Radius of the cylinder = 7 cm

Answer» ANSWER :- Given : Diameter of the base of right circular cone = 21 cm Height = 14 cm To FIND : The curved SURFACE area of the right circular cone. Solution : $\sf Radius \: of \: the \: right \: circular \: cone \: = \: \dfrac{21}{2} \: cm \: = \: 10.5 \: cm$ Let's find the slant height (l) of the right circular cone first. $\boxed{\sf Slant \: height = \: \sqrt{ {r}^{2} + {h}^{2} }}$ $\sf\longrightarrow \sqrt{ {10.5}^{2} + {14}^{2} }$ $\sf\longrightarrow \sqrt{ 110.25 + 196 }$ $\sf\longrightarrow \sqrt{ 306.25 }$ $\sf\longrightarrow 17.5$ .°. The slant height of the cone = 17.5 cm Now, We know that, $\boxed{\sf Curved \: surface \: area \: of \: cone \: = \: \pi \times r \times l}$ [where r = radius and l = slant height of the cone] $\sf\longrightarrow \dfrac{22}{7} \times 10.5 \times 17.5$ $\sf\longrightarrow \dfrac{22}{7} \times \dfrac{105}{10} \times \dfrac{175}{10}$ $\sf\longrightarrow 577.5$ HENCE, the curved surface area of the right circular cone is 577.50 cm²

36.

the diameter of the base of a right circular cone is 21 cm and its height is 14cm .its curved surface area is

Answer»

ANSWER :-

Given :

Diameter of the base of right circular cone = 21 cm

Height = 14 cm

To FIND :

The curved SURFACE area of the right circular cone.

Solution :

$\sf Radius \: of \: the \: right \: circular \: cone \: = \: \dfrac{21}{2} \: cm \: = \: 10.5 \: cm$

Let's find the slant height (l) of the right circular cone first.

$\boxed{\sf Slant \: height = \: \sqrt{ {r}^{2} + {h}^{2} }}$

$\sf\longrightarrow \sqrt{ {10.5}^{2} + {14}^{2} }$

$\sf\longrightarrow \sqrt{ 110.25 + 196 }$

$\sf\longrightarrow \sqrt{ 306.25 }$

$\sf\longrightarrow 17.5$

.°. The slant height of the cone = 17.5 cm

Now, We know that,

$\boxed{\sf Curved \: surface \: area \: of \: cone \: = \: \pi \times r \times l}$

[where r = radius and l = slant height of the cone]

$\sf\longrightarrow \dfrac{22}{7} \times 10.5 \times 17.5$

$\sf\longrightarrow \dfrac{22}{7} \times \dfrac{105}{10} \times \dfrac{175}{10}$

$\sf\longrightarrow 577.5$

HENCE, the curved surface area of the right circular cone is 577.50 cm²

Answer»

GIVEN that,

BC = 15m

AB = ?

∠B = 30 degree

we know,

AB/BC = TAN 30°

AB/15m = 1/√3

√3×AB = 1×15m

AB = 15m/√3

AB = 3×5/√3

AB = √3×√3×5/√3 ( 3 can be written as √3×√3 = (√3)^2 = 3)

AB = 5√3m

Therefore, the height of the TOWER is 5√3m.

manish and rohit complete a work in 20 days. rohit alone can do one fourth of the work in 15 days. In how many days will manish alone can complete a work

Answer»

Answer:

So in one day, A can do 1/15 th of total work.

In 8 days, A did 1/15 * 8 = 8/15 th of total work.

Remaining work 1 - 8/15 = 7/15

A+B did 7/15 th work in 4 days

Out of 7/15 , 4/15 th work was DONE by A

So all in all, in 4 days, B did 3/15 th of total work.

And in one day B can do 3/60 th of total work.

So B will REQUIRE 60/3 =20 days to COMPLETE the work alone.
